Leverage is a common financial transaction system, namely margin system

Leverage trading is also called virtual trading and deposit trading. That is to say, investors use their own funds as guarantee to enlarge the financing provided by banks or brokers to carry out foreign exchange transactions, that is, to enlarge the trading funds of investors. The proportion of financing is generally decided by banks or brokers. The larger the proportion of financing is, the less capital customers need to pay

leverage trading operation process:

1. Take BTC / usdt as an example, if the platform supports up to three times leverage

when judging that the price of bitcoin will rise from 10000 usdt to 20000 usdt, if you have 10000 usdt of principal, you can borrow up to 20000 usdt from the platform. Use 30000 usdt to buy 3btc at the price of 10000 usdt and sell it at the price of 20000 usdt, with a profit of 3btc * (20000-10000) = 30000 usdt

2. Take BTC / usdt as an example, if the platform supports up to 3 times leverage

when it is judged that the price of bitcoin will drop from 20000 usdt to 10000 usdt, with a principal of 10000 usdt (0.5btc), you can borrow 1btc from the platform, sell one bitcoin at 20000 usdt, and buy it at 10000 usdt, making a profit of 10000 usdt

if you only trade with your own funds, you can only buy low and sell high, not short

3. Calculation method of leverage lending rate:

from the time of applying for leverage, the interest will be calculated as 24 hours in less than 24 hours, and the loan funds and interest will be returned when the leverage is returned

4, the risk of leverage Trading:

leverage makes use of less capital to realize the possibility of obtaining greater returns. But if the wrong direction of the transaction is judged, the loss will also be enlarged year on year. Therefore, ordinary traders try to avoid the high leverage of heavy trading, to prevent the occurrence of burst positions or even through positions

(1) reasonable use of leverage ratio and control of position

(2) stop profit and loss timely and close positions spontaneously

(3) margin should be added in time to ensure that the ratio of total assets to leverage is greater than 110%

the user enters the loan management and selects the loan account to apply for loan assets.
